It would be useful because its hard to find people in the Curseforge server and you end up having to wait days or sometimes even months. I would expect this feature to be implemented in a little button on the left of the Curseforge sidebar. If you want to host a modpack or any mod then you could attach it to the group post and the contact area should consist of platforms like Discord so that people can contact you and a group description with filters for region/timezone, age requirement, mod amount, server playstyle, type, and much more. This simplifies the process from many Curseforge or mod servers and connects them all using one feature. There is even opportunity for ads and there could be multiple sections like make server, find server, and in-development mods can be promoted before they are released and when they finally are they will be notified. I feel like this is a great idea to bring together the entire community because its so diverse even though the modding scene has gotten insanely advanced.
